3 Claims.

This invention appertains t rotary tillers and .soil pulverizers of the type shown in my Patent 2,025,494, issued December 24, 1935, and more particularly to a novel means for mounting the tiller on a supporting frame and is an improvement on my Patent 2,347,017, issued April 18, 1944.

One of the primary objects of my invention is to provide a fixed land roller supported frame, so as to prevent swaying or tilting of the frame with novel means for hingedly mounting thetiller in the frame, whereby the tiller can conveniently be raised or lowered on the frame through a suitable mechanism, such as a hydraulic lift device.

Another salient object of my invention is to provide means for not only hingedly mounting the tiller on the frame, but for also resiliently suspending the tiller, so that said tiller will be free to give if the tines encounter solid objects whereby injury to the tiller will be prevented.

A further important object of my invention is the provision of novel means for mounting the rotary tiller on the frame in such a manner that the resilient supporting means therefore will not interfere with the operation of the hydraulic lift mechanism.

A still further important object of my invention is to provide an improved mounting for my rotary tiller, which will be strong and rugged in use and one that can be manufactured and placed upon the market at a reasonable cost.

With these and other objects in View, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a side elevational view of my improved device with parts thereoi` broken away and in section to illustrate structural detail.

Figure 2 is a top plan viewof my improved frame and supporting structure.

Figure 3 is an enlarged fragmentary transverse sectional view through the device taken on the line 3-3 of Figure 1 looking in the direction of the arrows, showing my novel mounting.

Figure 4 is a similar sectional View with the section taken on the line 4-4 of Figure 1 looking in the direction of the arrows.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter' M generally indicates my improved machine and the same includes a rigid or i'lxed supporting frame F in which is mounted the rotary tiller or soil pulverizer T. The rotary soil pulverizer T is mounted within the frame by my novel supporting mechanism S.

The rotary tiller T can be of the same type and character as shown in my Patent 2,025,494 and hence the same includes the rotary earth working element 5 carrying a plurality of resilient tines 6. The member 5 is rotated through the medium of a drive shaft 'I from the power take off of a pulling tractor (not shown).

My novel frame F includes a pair of spaced parallel frame beams 8 and 9, which can be formed from channel iron, if so desired. The rear ends of the beams 8 and 9 are rigidly connected together by a rear cross beam I0. The forward terminals of the side beams 8 and 9 are inclined inwardly toward one another and the longitudinal center of the frame as at I I and these beams terminate at a forwardly projecting draft beam I2. The forward end of the draft beam I2 carries a coupling E3 so that the machine can be attached to a tractor and I prefer to use that type of coupling shown in my Patent 2,347,017.

The frame F also includes a front transversely extending cross beam I4, which is rigidly fastened to the side frame beams 8 and 9. Rigidly fastened to the cross beam I4 is an upright frame plate I5 and this plate is firmly braced by struts I6 which extend from the plate forwardly into engagement with the forward ends of the side beams. Formed on or rigidly fastened to the upper corners of .the plate I5 are rearwardly projecting pivot lugs or Wings I'I and these lugs or wings form the support for the transversely extending pvot shaft I8. The plate I5, the lugs Il and the shaft I8 all form a part of my novel support S for the tiller T.

The support S also includes a pair of spaced parallel rigid frame plates I9 which are securely welded or otherwise fastened to the front of the tiller T and these frame plates I9 form a direct part of said tiller and project forwardly therefrom toward the upright plate I5. Disposed between the rigid frame plates I9 are a pair of spaced parallel triangular shaped connecting plates 20. The plates 20 are firmly united together by an upper cross rod 2 I, the terminals of which are rigidly fastened to said connecting plates. The lower rear corners of the plates 20 are rockably mounted upon a cross pivot shaft 22, which is carried by the lower ends of the rigid frame plates I9. The forward upper corners of the connecting plates 20 are rockably mounted upon the cross or pivot shaft I8.

In order to provide the resilient mounting or support for the tiller the rigid frame plates have tiller T on the cross shaft 22 is limited and arrested by the springs 26. Y

In order to permit the convenient raising and lowering of the tiller T on the frame F I provide an hydraulic lift. This mechanism includes a cylinder 28, the inner end of which is rockably mounted on the front transverse cross beam I4, as at 29. Mounted for reciprocatory movement in the cylinder 28 is a piston (not shown) carrying a rearwardly extending piston rod 30 and the rear end of this piston rod is rockably mounted upon the cross shaft 22. The hydraulic lift mechanism is of a, type which can be purchased in the open market and forms no part ofthe invention per se and hence the same is not described in detail. However, iiow of uid to the opposite ends of the cylinder controls the direction of movement of the piston and the consequent raising andv lowering of the tiller in the frame. It being obvious that the tiller will swing on the shaft I8 when the hydraulic lift mechanism is actuated. The control valve mechanism for the cylinder can be located on the tractor within convenient reach of the operator.

While I have stated that the tiller is lifted through a suitable hydraulic mechanism, it is to be understood that` a mechanical raisingv and lowering mechanism can be employed.

The rear end of the frame F is supported by a transverse extending land rollery 3l. This land roller extends entirelyacross the machine in the same manner as shown in my Patent No; 2,347,017 and the ends of the shaft for the roller are mounted in suitable bearings carried by the l beams 8 and 9. Attention is called to the fact, however, that the land roller 3| is corrugated to provide a series of annular ribs, which are of a V-shape in cross section.

From the foregoing description, it can be seen that I vhave provided a simple but sturdy means for resiliently and hingedly supporting'the tiller. T within a rigid or fixed land supported frame.

Changes in details may bev made without departing from the spirit or the scope of my invention, but what I claim as new is:

l. In a machine for working,1eveling and packing soil in one operation, a rigid frame including spaced parallel side beams, a rotary land roller carried by the rear end of the frame and rotatably supported on the side beams, a coupling member for connection with a tractor carried by tween the frame and the tiller.

the front of the frame, and a rigid transversely extending upright supporting member secured to the frame, a rotarytiller mounted between said side beams between the land roller and the coupling member, forwardly extending spaced parallel frame plates carried by the rotary tiller, connecting plates rockably mounted at their lower ends on said spaced plates, means hingedly mounting the connecting plates to the upper end of the upright member, a resilient connection between the pair of frame plates and the connecting plates, and a hydraulic lift mechanism be- 2.
